we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form y/x=k or y=kx

In a direct variation the equation of the line passes through the origin

In this problem we have

2y=5x+1 ----> this line not passes through the origin

therefore

<u>The answer is</u>

the equation does not represent a direct variation

It does represent a direct variation.

Direct variation: y = kx
y varies directly with x

Your equation 2y = 5x + 1 is in the form of y = kx but we need to divide out the 2 from 2y so we have the following
2y = 5x + 1
2y / 2 = 5 x/ 2 + 1/2
y = 5x / 2  + 1/2
y = kx
k = 5/2
k = constant of variation = 5/2

ratelena [41]

Answer:

a. Cottonseed oil freezes at a lower temperature than palm oil because          –48.1 °C < 24.1 °C

Step-by-step explanation:

–48.1 °C is lower than 24.1 °C since it lies on the negative side of the number line. Thus, Cottonseed oil freezes at a lower temperature than palm oil
